Researchers from the University of Arizona have conducted a groundbreaking study on the impact of human activities on Earth’s deep subsurface, located hundreds of meters below the surface. The study revealed that human activities such as oil and gas production, geothermal energy production, and lithium extraction are significantly affecting the circulation of fluids in the subsurface.
According to the research findings, the rates of fluid production induced by human activities far exceed the natural background circulation of water. Furthermore, human-induced fluid fluxes are predicted to increase even further with proposed solutions for climate change, including geologic carbon sequestration and geothermal energy production.
The study was conducted in collaboration with researchers from various institutions around the world, who stressed the importance of responsible management of the subsurface for a sustainable future and to address climate change effectively. Not only do human activities have the potential to alter deep subsurface fluids, but they can also impact the microbial communities that reside underground.
Despite significant advancements in the field, there are still many unknowns about Earth’s deep subsurface and its influence on human activities. The researchers emphasized the urgent need to understand and harness the deep subsurface as part of the solution to the global climate crisis.
This study sheds light on the crucial role that the deep subsurface plays in the Earth’s ecosystem and underscores the importance of ensuring sustainable practices to safeguard this vital resource for future generations.
